This is a self-heating mask that promises to open pores to give skin a deep cleanse. Montagne Jeunesse recommends you leave it on for 10-15 minutes before washing it off.

I’ve now tried this mask, and I’m disappointed. I bought this mask recently, but most of the product had turned into a solid mass inside the sealed sachet.

I was able to use some of the product, however, the self-heating effect was non-existent, and the mask didn’t really do anything for my skin at all.

The sweet chocolate-orange fragrance was still spot on. But it didn’t matter.

All in all, I’m disappointed. I think it’s possible this is old stock. However, I would expect the manufacturer to be aware of the rather limited shelf life of their products, and I would also expect them to print a use by date on such products.

Montagne Jeunesse Choc Orange Sauna is available as 15g. I paid 90p. This mask is approved by the Vegetarian Society, and it’s certified cruelty-free (it carries the Leaping Bunny logo).
